I will graduate from elementary school soon .
6-year learning is coming to an end. I clearly know that I'm going to a junior high school soon.
I have heard that the study there is much harder than that in primary school. So I have to work hard to achieve a new height. First I will read lots of books so that I can get ready for the future learning. Then I will do some practice. As the saying goes: Practise makes perfect.
In a word I will try my best!

很快，我就要从小学毕业了。
六年的学习快结束了，我清楚地知道我马上就要去初中了。
我已经听说那儿的学习比小学的要难很多。所以我必须努力学习以达到一个新的高度。首先，我要读很多书以便我能为将来学习做准备。然后，我要做很多练习，就像一句谚语说的那样：熟能生巧。
总之，我将尽我全力。
